The Jones County sheriff said a woman's body was found Friday evening more than a mile downstream from where her car was discovered. Earlier that day, two fishermen had alerted police to the car, which was in four to five feet of water with one door open.

The Anamosa Community School District identified the victim as Nicole Cox, 30, an elementary guidance counselor for the district. Cox lives in Stanwood.

The district said counselors will be available at the school Saturday and a candlelight vigil will be held at 8 p.m. at Wapsipinicon State Park.

Authorities are investigating how Cox's car ended up in the river. An autopsy was scheduled for Saturday.
